The boundary conditions provided by DC current-limiting reactors facilitate the design of fault protection algorithms. The voltage-drop characteristics of the current-limiting reactor and the shunt characteristics of adjacent lines are combined in this paper. Then a pilot protection scheme for DC lines based on boundary transient energy is proposed. The difference of the transient energy ratio at the boundary of the line is used to identify internal faults and external faults. Then the transient energy ratio of the positive and negative poles can be calculated to identify the faulty pole. The characteristics of the fault boundary are obviously different under different faults. The implementation of the scheme is simple and there is no need to synchronize data at both ends of the line. The proposed scheme is tested in a four-terminal MMC-HVDC system and the results show that the scheme has the ability to fast and accurately identify faults. It has sufficient sensitivity to faults with large transition resistance, and has strong anti-noise ability.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122907826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a voltage regulation method based on deep reinforcement learning to reduce the voltage fluctuation in the distribution network with battery energy storage system (BESS). The operation of battery energy storage system is modelled as a Markov Decision Making process. Then, by embedding a deep Q-network to obtain the optimal charge and discharge strategy, the calculation problem caused by too large state space could be efficaciously solved. Furthermore, the deep Q-network will be trained by replay strategy to achieve iterative convergence. And an intelligent BESS control method that provides auxiliary service for voltage regulation is ultimately obtained. Finally, the modified IEEE33 node system with BESS is analyzed by using Matpower in the framework of TensorFlow, and the effectiveness of the proposed method is proved.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123204487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing electrochemical energy storage involved in frequency modulation fails to balance the result and the economy of frequency modulation. The configuration of frequency modulation capacity needs to be further improved. The article gives the current status of domestic and foreign research on energy storage, taking part in power grid frequency modulation, and analyzing the market mechanism. It analyzes the capacity allocation of energy storage participating in frequency modulation and reviews the effect of frequency modulation and economic efficiency. The financial analysis involves.

So the wind farm fails to maximize the output power, and the contribution of the wind farm to participate in frequency regulation will reduce. In order to fully tap the potential of wind farms participating in system frequency regulation under actual conditions, this paper adopts the Jensen model to establish a wind farm power optimization model considering the superposition of wake effects under actual operating conditions. The interior point method is used to coordinate the axial induction factors of each wind turbine to optimize the output of the wind farm. Furthermore, since the fixed droop coefficient cannot well reflect the ability of wind turbines participating in frequency regulation under different wind speeds, a variable coefficient droop control strategy is proposed for wind farm to participate in the primary frequency regulation optimally. Simulation studies are carried out to demonstrate the effectiveness of the proposed strategy.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114321349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
